Mixing Tangs
Based on my experience, fish are like people and have attitudes. I had a pesky yellow tang that wanted to own the aquarium (250gal). He stressed out my Naso and PBT to the point I had to get rid of him. My BNT and BPT swim together and are happy he's gone, go figure..one little different colour and different shaped tang can mess up the community. I would suggest buying a very large tank for them as well. Even when small, they think like they are big. If you want tangs, especially Naso or Hippo think 200 plus gallon for the tank. My rule of thumb is to remember what worked before, doesn't always work again. Always keep an eye on their behavior. Research each fish individually and then again for compatibility.When adding a new Tang (after 2 week quarantine) feed your existing fish first.You can change something in the tank, like moving a rock, nothing drastic,the tangs are very curious and will pay attention to that change as much as than the new roommate, at least until feeding time!
